Hi,

Data to display on the map is loaded using a GeoJSON and it contains a range of Points, MultiLineStrings and Polygons.

I would like to know is it possible to pass on styling information in the GeoJSON like how CZML does.

Currently I am doing the following to style it:

````auto
const entities = dataSource.entities.values;
      for (let i = 0; i < entities.length; i++) {
        const entity = entities[i];

        //Set the polygon material to our random color.
        if (entity.properties.entity._value !== null &&
          entity.properties.entity._value.toLowerCase().includes('line')) {
          entity.polyline.material = new Cesium.PolylineDashMaterialProperty({
            color: Cesium.Color.DARKGREEN,
            dashLength: 8.0,
          });
          entity.polyline.width = 3;
          entity.polyline.clampToGround = true;
        }
      }```

If it is possible to pass on the style in GeoJSON it would make it easier.

Any help is highly appreciated.

Thanks

If you mean through the GeoJSON file itself, styling is quite limited, however Cesium supports SimpleStyle (originally from MapBox). Look at this Sandcastle for demo and more info in the comments;
